Abstract
The present invention makes it possible to perform machining that forms holes or grooves for the attachment of parts to the outer circumferential edge surfaces of lenses of various lens patterns, both accurately and with good reproducibility, by means of a simple operation. The spectacle lenses are positioned so that the machining areas of the spectacle lenses are maintained in a fixed positional relationship with the machining reference position of the machining apparatus by using spectacle lens fastening devices which can fasten the spectacle lenses with attached spectacle lens holding jigs in place, and adjust the positions of these spectacle lenses , to cause specified positions on the spectacle lenses to contact the reference surfaces of a positioning reference plate
